Medical Physiology

Medical Physiology

The course takes a systems approach to physiology. The goal of medical physiology is to explain the specific characteristics and mechanisms of the human body that make it a living being. Medical physiology teaches the crucial processes that are responsible for the origin, development and progression of life. Due to the close interrelationship between structure and function in biological systems, each functional physiology topic will include a brief overview of anatomic structure. The physical and chemical laws that are the basis of the physiological processes will also be covered.

In order to foster active learning and to develop presentation skills, students will be expected to present the selected topics of physiology during two semesters of the course. Distributed well in advance, all students will have adequate time to prepare using their lecture notes, readings, and internet.

The laboratory exercises in physiology will enable students to evaluate and draw conclusions from data, become familiar with methods of obtaining information in a biological system, and in general help them in the future to evaluate claims concerning new methods of therapy and to read the scientific literature more critically. Laboratories will furnish students with the very valuable experience of working with human subjects and developing manual dexterity.
